⢠Available in 28 pin DIP, SDIP, or SOIC packages
⢠Interfaces to any microcontroller or microprocessor
⢠Cost effective for OEM applications
The EDE707 seven-segment LED controller handles up to eight 7-segment LED displays,
tremendously reducing I/O demand on your host microcontroller as well as eliminating display
refresh/scan software overheads. Data is written to the display via a 4-bit data bus using an active-
low latch pin. Display data is sent to the unit in BCD (binary-coded decimal) format and is
continuously displayed by the EDE707 until the host system provides new data. The EDE707 offers
a valuable feature set, including leading zero blanking, counter functionality, an overflow flag, and
a full 0-9,A-F Hex character set.
